A few weeks ago I was in the mood to buy a new bike helmet before the start of summer. I had planned on buying the super-lightweight Giro Ionos Road Bike Helmet because its massive air vents were very appealing to me. When I tried the Giro Ionos on in the store it was very comfortable. However, when I got down into the position like I would normally be in when riding in the drops I could easily see the bottom edge of the helmet above my sun glasses. As a result, I started looking for another brand of helmet and settled on the Trek Circuit Helmet.
Trek Circuit Helment
The Trek Circuit Helmet is only slightly heavier than the Giro Ionos, but about $130 less (the Giro Ionos retails for $230, while the Trek Circuit retails for $100). While at the bike shop I held the Giro Ionos in one hand and the Trek Circuit in the other and the difference in weight was very insignificant.
The Trek Circuit Helmet has 21 well-placed vents that provide excellent air flow. Trek’s ZipTite 2 fit system is excellent and the helmet is so light and fits so well that it is easy to forget you are even wearing it. I rode over 500 miles with this helmet in the past few weeks and would highly recommend it to any cyclist.
